1Introduction
Data Migration Service (DMS) is a new block level, offline data migration service
introduced in the HP StorageWorks MPX200 Multifunction Router (MPX200) data
transport device. The HP StorageWorks mpx Manager software is designed to
simplify data migration jobs for minimum downtime, while providing protection
against common user errors.
This chapter provides a high-level Features Overview, and also details of each of
the following features:
“Job Scheduling” on page 1-3
“Data Migration Job Groups” on page 1-4
“Array Properties” on page 1-4
“Protection” on page 1-6
“Data Migration Jobs” on page 1-6
“Logs” on page 1-8
“Users” on page 1-8
Features Overview
The Data Migration Service technology deployed on the MPX200 with the HP
StorageWorks MPX200 Multifunction Router software has following features:
Fibre Channel SAN vendor independent: The MPX200 supports
Brocade®/McDATA®, Cisco®, and QLogic Fibre Channel fabrics. HP
StorageWorks mpx Manager allows data migration across multi-vendor
fabrics.
Heterogeneous array support: HP StorageWorks mpx Manager supports
data migration across heterogeneous arrays (arrays manufactured by
different vendors). For a list of the storage array types for which DMS
currently provides support, see “Supported Storage Arrays” on page 2-4.
Ease of use: HP StorageWorks mpx Manager is designed to be extremely
simple to use. The graphical user interface (GUI) and command line
interface (CLI) provide many wizard-based operations and user-level
protection.

1–Introduction
Feature Details
1-2 ISR654606-00 A
Data security and sanity: HP StorageWorks mpx Manager provides
features to classify a storage array as “source only,” making it impossible to
write data to that array and thus minimizing the chances of data corruption. It
also provides a Verify Migration Job wizard to compare data on the source
LUN with that on the destination LUN to indicate that the data copy occurred
without any data loss or corruption.
Migration job scheduling: Data migration may be disruptive to
business-critical applications; therefore, minimizing application downtime is
very important. DMS provides several job scheduling options, including the
Configure Only option, which allows you to complete the time-consuming
task of configuring data migration jobs without requiring any downtime. The
different I/O size capabilities for migration jobs enables you to tune the
storage array’s performance during sequential read/write operations. The
Load Balancing option is also very useful when dealing with
older-generation, lower-speed arrays (such as 2Gb and 4Gb Fibre Channel)
being migrated to higher speed (4Gb and 8Gb Fibre Channel) arrays using
higher-speed (4Gb and 8Gb) Fibre Channel switches.
Data migration service logs: DMS logs are maintained separately from the
system logs. DMS logs are designed to help the service professional
maintain a full, detailed history of each job performed, and can be submitted
as a part of the migration report to the customer.
Logging and troubleshooting: System logs are designed to store a
significant number of details that can be used for debugging and
troubleshooting. The save capture command (see “save capture” on
page 5-57) helps to capture the configuration details, system logs, and
MPX200 state at any time, and can be used for troubleshooting if the need
arises.
Licensing: DMS licenses provide capacity- (per TB) and array-based
licenses. For more information, see 4 Data Migration Licenses.
Feature Details
This section describes the features of the Data Migration Service. Because the
current DMS is an offline-only service, it is assumed that when a data migration
job for the specified LUN starts, applications (Microsoft®Exchange, Oracle®
Applications, and other applications that are using the source LUNs for data
storage) and server access to the LUN is blocked. You do not need to bring down
these applications during the initial setup and configuration of DMS. DMS
minimizes the downtime by allowing the complete setup and configuration of data
migration jobs (except for immediate scheduling of the jobs) without bringing down
the other applications. The application and server must be offline only during the
actual data migration.

1–Introduction

ISR654606-00 A 1-3
Job Scheduling
HP StorageWorks mpx Manager provides multiple data migration job scheduling
options to optimize bandwidth and provide maximum usage of SAN resources. It
provides a priority-based serial scheduling feature that enables you to line up
migration jobs and execute them in serial or parallel fashion, based on available
resources.
You can schedule data migration jobs for execution in the following three ways:
Immediate Schedule (start now)
Delayed Schedule (start at a later time within the next 30 days)
Serial Schedule (priority-based scheduling)
Immediate Schedule
Use the Immediate Schedule option to schedule a data migration job to instantly
start data migration. You must ensure that both the source and destination LUNs
are not being accessed by any application when this option is selected.
Delayed Schedule
Use the Delayed Schedule option to schedule a data migration job to start at a
later time. When you select this option during configuration of a migration job, you
are requested to enter the start time. This allows you to configure a migration job
during normal business hours and perform actual data migration during off peak
hours, so that the application remains down only for a short period of time and
during the off peak hours.
Configure Only
The Configure Only option enables you to configure migrations jobs without a
specified start time. With this option, you must start the migration jobs when
system downtime begins. This option is very useful when the exact downtime of
the application is not known. Use this option when you need to configure all
migration jobs without requiring any application downtime.
Serial Schedule
The Serial Schedule option is designed to provide maximum flexibility for data
migration. Even though DMS supports 256 simultaneous migration jobs, typical
array performance can be maximized by having only 4 to 8 LUNs under migration.
Serial scheduling of the job allows configuration of all 256 jobs at the same time,
while having fewer active jobs at a time.

1–Introduction
Feature Details
1-4 ISR654606-00 A
Serial scheduling allows you to configure migration jobs that can have the same or
different priority. If you need to configure a large number of jobs (256, for
example), you can configure them in batches such that the first four to eight jobs
are scheduled at priority 1, the next four to eight jobs at priority 2, and so on. This
scheduling arrangement ensures that when the serial schedule starts, no more
than four to eight jobs are running simultaneously, and DMS can provide better
performance.
In order to achieve this, serial scheduling requires a job priority for each data
migration job. Multiple data migration jobs can have the same priority. Migration
jobs with the same priority are run together. Job priority 1 is highest and job
priority 255 is lowest. After all the jobs are configured for serial execution, you
must schedule this batch of serially-scheduled jobs. The batch can be started
immediately or at a later time. The Serial Data Migration Jobs Options dialog box
provides an easy way to start or schedule the batch.
After the serial batch starts to run, all jobs having the highest priority are
completed before the jobs scheduled at the next priority level start to execute.
Only one serial schedule can be active at any time.
Data Migration Job Groups
The mpx Manager uses the concept of job groups to associate data migration jobs
with user-defined groups. A job group allows better management of data migration
jobs. You can create a maximum of eight job groups. The mpx Manager also has
commands to remove and edit job groups.
The groups can be classified for data migration jobs related to application type or
server class. For example, a data migration job related to the Microsoft Exchange
application could be part of group named “Exchange,” and a data migration job
related to a payroll application could be part of group named “Payroll.” The data
migration jobs are tracked separately within each group. You can schedule the
data migration of all LUNs related to one application, followed by other
applications.
If no group is defined, all jobs are assigned to the default group, Group 0. You
cannot delete Group 0.
Array Properties
DMS discovers the Fibre Channel target ports and forms an array when at least
one data LUN is presented to the DMS running in the MPX200 from that array. If
no data LUN is presented to the MPX200, all array ports are shown in the mpx
Manager GUI and CLI as target ports. After the LUNs are presented to the
MPX200, a target rescan is required to form an array (see “target rescan” on
page 5-56).

1–Introduction
Feature Details
ISR654606-00 A 1-5
DMS classifies the discovered storage array controllers into two categories:
targets and arrays. All array controller ports are initially identified as targets by the
MPX200. After a single data LUN is detected on the target, DMS forms an entity
called an array. A specific LUN seen through multiple Fibre Channel target ports
are grouped under a single array.
Configure the array entity created by the DMS for the following attributes:
Symbolic name: Upon forming an array, the HP StorageWorks MPX200
Multifunction Router automatically assigns a symbolic name to an array.
QLogic highly recommends that the you assign a more meaningful name to
an array because the migration logs identify the source and destination
LUNs with the symbolic names of the source and destination arrays.
Array type: DMS requires the classification of each array as either Source,
Destination, or Source+Destination. During the creation of migration jobs,
the Data Migration wizard restricts the assignment of a source LUN only
from arrays that have an attribute Source and assignment of a destination
LUN only from the arrays with attribute Destination. Use the array attribute
Source+Destination only when you need to create copies of a LUN on the
same array.
Select the array type attribute None to exclude the storage array from
participating in data migration. The MPX200 simultaneously supports both
iSCSI connectivity and data migration service. Typically, you would use the
“None” attribute when the MPX200 is used to provide only iSCSI
connectivity for that storage array.
Array bandwidth: This feature is applied only to a source array. This value
indicates the maximum bandwidth available from the array for a data
migration task. The bandwidth is computed over all paths. The MPX200
uses only the user-assigned array bandwidth to migrate the data. This
allows other applications and servers using the same source array to
continue to perform at an acceptable performance level.
Load Balancing: The MPX200 detects all available multiple active and
passive paths to the LUN. Load balancing balances the load for migration
jobs over multiple active paths, thus improving the migration rate. Load
balancing should be disabled only in case of trouble performing data
migration.

1–Introduction
Feature Details

Protection
DMS provides data protection against some of the common user errors by
enforcing the following restrictions:
An array must have an attribute of either Source, Destination, or
Source+Destination to participate in the migration. When you configure a
data migration job, Source LUNs can be assigned only from an array with
the attribute Source (or (Source+Destination), and Destination LUNs can be
assigned only from an array with the attribute Destination (or
Source+Destination). Use these attributes properly to avoid errors.
A user acknowledgement is required for a data migration job after the job is
completed. This feature provides better accounting and record-keeping for
the job. The data migration log indicates when the job was completed and
when you acknowledge the completion status of the job.
After a LUN is configured as a Destination LUN for a specific data migration
job, the LUN cannot be configured for a different job until the current job is
completed and you acknowledge or remove the job.
DMS detects the normal configuration of partitions on the data LUN. Before
fully configuring a data migration job, DMS provides a warning if it detects
valid partition tables on the destination LUN.
Data Migration Jobs
DMS manages the data migration processes in terms of data migration jobs. A
maximum of 256 jobs can be scheduled to run at any time.
Data Migration Job Attributes
Configure a data migration job for the following attributes:
Source and Destination LUN: You can configure a single source LUN to
migrate to one or multiple destination LUNs. Any specified destination LUN
can be part of a single data migration job.
Job groups: For better manageability, you can configure data migration
jobs to belong to a specific, user-defined job group. By default, a job is
assigned to a default group, Group 0.
Scheduling: You can configure data migration jobs to start immediately, to
start at a specified time, to have no start time (configure only), or to use a
priority-based serial scheduling. For details, see the “Scheduling...” sections
under “Using the Data Migration Wizard” on page 3-7.
I/O size: You can configure each data migration job to migrate data using a
specified I/O size. Different types of arrays and LUNs may provide optimum
performance based on the I/O size. The default size is 64K.

1–Introduction
Feature Details
ISR654606-00 A 1-7
The Data Migration wizard enables you to configure multiple jobs in a batch mode.
The jobs configured in batch mode have the same common attributes. For more
details, see “Using the Data Migration Wizard” on page 3-7.
Data Migration Job States
Table 1-1 lists the possible data migration job states.
Data Migration Job CLI Commands
DMS provides CLI commands (migration stop/start/pause/resume) to
alter the state of the migration job. The migration stop/start command
causes a job to be stopped and then restarted from the beginning. The
migration stop command rewinds the job to the beginning.
You can use the migration pause/resume commands only on running jobs.
The migration pause command causes the job to halt temporarily. The
migration resume command causes the job to resume from the point where it
was paused; it will not start from the beginning of the LUN. Pause a migration job
if it is taking a lot of array bandwidth and causing other processes on the array to
slow down. You can later resume the job when the I/O activity on the array is
reduced.
Table 1-1. Data Migration Job States
Job State Description
Running Job is currently running. You can pause or stop a running job.
Scheduled Job is waiting to be run.
Completed Job is complete. You must acknowledge a completed job.
Paused A running job has been interrupted.
Stopped A running, scheduled, failed, or pending job has been halted. You can
restart or remove a job in the Stopped state.
Failed The MPX200 lost access to the LUN during a data migration job, caus-
ing it to fail.
Pending A job configured for a delayed start (either due to Delayed Scheduling
or Serial Scheduling) cannot start at the specified time because the
source or destination LUN is offline. When the LUN becomes online,
the job will go into the Running state. If you determine that the specified
LUN will never come back online, you can remove the pending job.

Logs
DMS manages the following two log types:
Migration logs: Migration logs provide a detailed history of each data
migration job. The job history contains information such as the start and end
time of the job, source and destination LUNs and arrays, size of the job, total
time consumed for the job, and so on. Using the HP StorageWorks mpx
Manager GUI, you can export the migration logs out of the MPX200. You
can open this file with a spreadsheet application such as Microsoft Excel
and use it as a data migration task report. QLogic highly recommends that
you save migration logs after the data migration job is completed and
cleared from the MPX200. This provides a record of every data migration job
and makes it easier to differentiate between them.
System logs: System logs primarily record events, errors, and configuration
changes, and can be used for troubleshooting.
Users
The MPX200 supports two types of users:
Administrative user: For managing the MPX200, you must be in an
administrative session. The default password for the administrator is config.
Data migration user (“miguser”): This user session is required to
configure migration-related activities. The default password is migration. For
all DSM functions, you must run a miguser session.
